Termites are estimated to cause $5 billion in property damage each year. Termites can nest for years before the damage is noticeable, so early detection and treatment is key. Here are some of the common signs of a termite infestation to look out for.

Blisters and Swelling in walls

Subterranean termites can cause damage that makes wood floors appear to have water damage. These blisters indicate that termites are feeding just below the flooring. The same is true for windows and door frames. If you know that your home has not sustained any water damage, get these spots checked by a pest professional.


Drywood termites consume wood from the inside out, often leaving just a thin layer of wood or paint on the outside. When tapped, this wood will sound hollow. These places may be difficult to detect until significant damage is done.


When termites are present, discarded wings can be found by windows, doors and other access points. When termites are ready to begin a new colony, they will swarm out of their nests to mate and search for a new place to live. When they land, termites will shed their wings, as they will not need them again. Sometimes, winged ants are confused for termites. Termite wings are both the same size, where ants have larger front wings and smaller back wings.

Mud Tubes

Pencil sized mud tubes along the foundation of your home are a sign of termites. These can also be found along any other source of food, such as trees or shrubbery. Mud tubes are used by subterranean termites to move above ground, as they require certain temperature and humidity levels to survive, and cannot travel in the open air. These tunnels help to shield them from cold, dry air.


Drywood termites like to keep their nests inside of wood clean. While tunnelling and eating, these termites will create galleries. To clear these galleries of waste products, they will create holes to kick out their excrement. Since drywood termites eat wood, their droppings, called frass, resemble sawdust or coffee grounds.

White Ants

While ants and termites look similar, there are several differences in the two species. The waist section of a termite is thicker than that of an ant. Termites are light in color, and can sometimes be translucent. There is no species of white ant, so if you believe you have “white ants”, you probably have an active termite infestation.
